Be it iinovn that @LAF A. ANDERSON,

citizen the Unite@ States, am). a esioeut oef Highland taik. iii the county of 'Wayne State of itiiehigan, have invent eri 'Jeff-taf new and useful improvements iii iiiictoi-iffheeis, 'of Whichuthc following is a speciicatioia.

idiy invention i'eiates to motos-Wheels ami has for an object to pioeiuce a setcontaiueci motor-Whse?. which may be attached to theA fem ferks of an ordinary bieycie in piace of the omiiuaiiy rear Wileei and may-,thusconveit the bicycle into a motorcycle. To accompiish this object to produce a motor-Wheel of simpiev construction and capable of inexpensive manufacture, i make use of a piuiaiity smaii gasolee motci's attached directly to the Wheei and Aotating therewith. i

ln order that my invention may Toe cieai'iy understood, E will describe in etai the em bcdimeut of it which is illustrated in the ao compauying drawings, in Whicifi y Figu'fye l is an end eievationypaiiiy in section, of my motor-wheel attachei to the Figi 2 is an eiiiarge fragmentary ViewY similar to Fig. l but showing one oir the motors iu section..

Fig. 3 is a sectional View of my Wheel taken at right-angles to the section shown in Figs. 1 and 2.,. said sectional View being horizm'itaiiy through that portion of the mecha-- mism shown at the left-hand side of Fig. 4i.

Fig. is a diagrammatic side-View of my .motor-Wheel showing the operative relation of the mechanisms contained in the Wheei, and JFig. 5 is a see-tional View7 corresponding with Fig; 3., through that potieii of the .eehaiism shown at toe fight-bandi side of fi. f

Wileei7 iiie ai?. oi ii'naiy bicyeie wiieei, is suppcfteei cy a xefi aide l passing tiiiough uoies in the iowe'f end of resi" ioris 2. Lpes the xe axle i is mountedt a fixed huh-3 and la fixed cone The spreeket-Wheei 5 is attached to the sprockeb hub 6, which is mounted by a bali-bearing Z upon the iiXefi cone 41.-. .Tae inuei" suiiace of the spioelet-iiub ii, is arangeci to engage an ordinary coastei-bi'aie to be insertefi in the space A.. Upon the outer emi of the zzed huh 3 is screwed a member eompi'isi the ami 8 which is attached to the sea? foei:

fiom iotating and the hieii the caibuieter 1G 1s to pyeyen'. tile hub 3 hollow arm 9, to w attached. The fixed gea-Wiieei is iii tegrai with i' atuaciieci to the i'ibefi iiub 3. fis shown iu the drawings, geaeviie il has a fiber in aunuiai strip of iibei i2, takes the piace of the .Qjeaitecth of an ordinai'y gear-Wheel.

Attach-eo. tc the right-hand. side oit the iixeci hub 3 is a iifzed baiiei i3, upon which the ixed vaivc Canis 14. 15, ILS, 17, ae mounted and heini in piace by a nut 18.

The rotar" part of the device ci Wheel proper consists ci' a shei composed of two sections 1S," 2), rigidly attached to each other. The outer periphery of the sheil-section is formed like the rim of an ordinary bicycie Wheel auc upon it is mounted the tire 261 fili the mechanism in the wiieei is attached to the sheitsection i9, so that the section 2O may easily be remove-.ii if it is necessary Le obtain access to the m ciianism. The left-hand shell-section 19 is mounted upon the fixed hub 3 by means of the bailiveniiug 22.7 While the iiggiioiiand section. 20 1s mounted upon the sprocket-hub G by means of the haii-bearing' 23. section `2G is eitenoied inwardly to 'forni the ievoiv lng barrei 24C, adapted to fit a'ouuri an. oi nary eoasteifhin'ske to bc piaceri in the space f. A bail-bearing 25 p i'ovied between 'tue rotary baiiei 24. and the ioiel side of the ied hub 3.

Two gaseiene nic-'tors are used in' the embodiment.. of my invention shown iii Ythe di-awings. These mot-ois are piaceai at diametiieally opposite points of the Wiieet shell anfi have t'ieii cylinders iangeii. The stank-case oi eaci. at the outer emi of .its eyiiudei. As the motors ae exactly alike, a description of one of them (shown best iu Figs. l and 2) Wiii. sufiice. The engine consists of a cwiocase 2'?, which. is rigidi y attached to siie'iiseeticn i9. To the iiuef emi. ef the ks case 2'? is attached the cyiiuoiez' 28 to tile inner end of the eyiimieii aie A 'i the intake munito-ici 2S and. the ediau'stf 30. The exhaust-pipe 3* best shown in Fig. (amends around the ca i-i)a11ei 'i3 and is at its ezfztiemity attache@ to die steli-sectie@ The e116?. the pipe 30 regstei's with iu sam I i shed-section.

The

meter cou.-

Vtures (not sheen wheel 38 meshes with the fixed gear-wheel l1 and has a planetary motion around that gear.

The g-asolene is supplied to the carburetor 'l0 from a tank carried upon the 'frame of the bicycle. The tank may preferably be hung from the upper bar of the frame.

rlhe explosive mixture is drawn 'to the motors from the carburetor l0 through the radial channels 42 in the lixed hub 3. The annular portion oit' the intake manifold :29 surrounds the ends of said radial channels 42 having a gas-light but running ht with the lined hub 3 at From the annular portion of the intake manifold the gas passes to lthe pipeshaped. portion which connects with the cylinder The valves 44, 45, Control the admission ot the mixture and the exhaust ol the products of Combustion from 'the cylinder. The stems ot' these valves rest iugon'lal'ches 46, i47, against which tiey are `forced by springs. lhe latches are hinged upon a pin 4 8 extending' from the exhaust'pipe 3G to the intake manifold 29, and ride upon the cams lll and 17.

A single carburetor l() supplies the eK- plosive mixture lor all the motors and a single intake manifold 25) connects with the cylinders of all the motors'.` A single 'fixed gear-wheel ll meshes with Athe gears of all the n'iotors'.

The ignition is accomplished by means of sparloplugs 9, i9. Electric current isV supplied e these pluies at the proper time by the magneto and timer 50 lgs. 3 and Ll). which is attached to and carried 'by the Wheel-shell. The magneto driven 'by a, geaiewheel il, waieh meshes with the fixed gear ll.

A blower 52 is preferably provided. In the drawings I have shown a small Sirocco blower attached to the wheel-shell opposite the dynamo. The blower is driven by a small gear 53 meshing` with the lined gear ll. The blower draws air through an aperture -l in the s-.iell section 20. A. screen 55 is plated across this aperture. rlhe air troni the blower f the pipes 56 to the cylinders the motel 'lhe air lea/yes the wheel-s l gli oney or more apen l which are preferably ,I is led l passes from the reservoir to the cylinders through the pipes 5S, 58. Part of 'this oil enters the hollow wrist-pin Fig, 2). The oil passes from the interior of the wrist-pin through an aperture 59 registering with the small bore 60 in the (See g flee air current serves td cool,I

connecting-rod 32. lA portion of the oil i lserves to lubricate the bearing of the connecting-rod on the wrist-pin, while part of the oil passes thuongrh the lbore (50 and lubricates the crank-pin bearino. The ballbearings\40, '41, as well as the bearings of the magneto phd the blower may be lubricated by oil carried from the reservoir to these bearings through small pipes. To avoid confusion, these Vpipes have not beenI shown in the drawings. "As the oil reseryoir is placed nearer the center of the wheel than the points at which the oil is used, the oil is fed to these points by 'centrifugal .torce when the wheel is rotated; It desired, the oil may be fed positively by a smell pump carried by the'wheel-shell and d1 .en by a gear meshing with the fixed gear ll'.

The operation of my motor-wheel is as ol-` lows: 'In starting, the rider rotates the." wheel ,by means of a pedal-ohainwhich passes around the sprocket 5. This rotation cranks the motors and also produces current from the magneto to cause the ignition. As soon as the explosions begin, the planetary motionof the gearovheels upon the motorshafts around the fixed gear 1l causes continued rotation of the wheel-shell. The rider may then cease pedaling and hold his feet still, as in ,coasting down hill with a. bicycle equipped with a eoastenbrake. The speed of the vehicle is controlled by inai'iipuiation of the throttlewalve 6l, 'which is connected to a controlling lever on the handle-bar or at seine other convenient point.

The ratio between the fixed gear-Wheel 1l and the gear-wheels upon the motor-shaft is S :1, so that if four-cycle motors are used, as shown in the drawings, each motor will have four explosions or power impulses for each rotation of the Wheel. The cams and timer are so arranged 'that the eXplosion-strole of one engine 'is simultaneous with an intake-stroke of the other motor. Considering` the two motors together, there tore, there are eight evenly-spaced pfower 'npnlses for each rotation olf the wheel.
